King is one of the hardest singers to cover...maybe the hardest one..you need to have an extremely control over your voice....you need to do the falsettos, the highest falsettos, the opera falsettos, the normal voice, the opera normal voice (like on the nightmare be thy name chorus), the growths, screams....wow...it's almost impossible..and that's the reason most of KD/MF covers sucks...and we must consider that most of KD/MF songs are really hard to play...(I can't say exactly cause I don't play any instrument, but I have the impression that most of their songs are really complex)

there are only 2 or 3 KD covers I really enjoy...aeon's cover is one of them, the best king cover I've heard....

this one sounds good too....I need to check more songs to be sure, but you have a great vocalist..

and of course there's only one king and no matter how good the guy who's singing is good, he will never be as good as king..
